To all whom it may concern.' I

Be it known that I, VALENTIN JAKOB ODHNER, a subject of the King of Sweden, andresident of Karlaplan 2, Stockholm, 1n the Kingdom of Sweden, haveV invented certain new and useful Improvements in Calculating-Machines, of which the following is a specification, reference being had therein to the accompanying drawings. l

This invention relates-to improvements in calculating machines of that class, which have a number of calculating wheels provided with radially movable pins, which are brought into operative position by means of curve disks rotatably `mounted `on the calculating wheels respectively and, as the ycalculating wheels are rotated, engage toothed wheels or the like for the shifting Vof the indicating disks of the machine. The invention relates especially to machines of the said construction, in which the calculating wheels are provided with laterally swingable pins, which are deiiected to run on the line of rotation of the pins firstmentioned, in order to kengage the said toothedv wheels and carry column of value. In order to prevent the indicating disks of the machine, when shifted, from rotating through a too *great` angle acted upon bythe 'momentum imparted to the said disks and `parts-belonging to the same,.when the calculating wheels are rotated very rapidly, it has beenproposed to lock the indicating `disks by means of starwheel's, which :bear preferably against the periphery ofthe calculating wheels respectively but for which a recess isprovided 4in the said periphery at the shifting ofthe pins, the length of which corresponds to the number of pins Y'brought into operative position', so that the lstar wheels and the indicating disks may be yrotated freely., when shifted by the said pins, but are then again locked. As machines provided with the said locking mechanism hitherto have been constructed the recesses provided in the circumferential surface of the Vcalculating wheels and necessary forthe transmitting of the tens, etc., always have been uncovered, owing to which fact vthe indicating disks are not locked,=while the said recesses pass by the star-wheels but there `would be a possibility-of an accidental rotating of the indieating disks,lif the latter are not provided with any other locking means. For the rep Specification of Letters `Patent. Patented Agg, 1920 1919. vSerial-N0. 292,981.

.moval of the said disadvantage vthe calculating disks according to this invention are provided for each ten pin etc. with a movable'part, which normally covers the said recess and locks the Vstar-wheel but, `as the ten pin etc. is'moved into its active position, is brought away, so that the star-wheel and the indicating disk may bel rotated by the ten pin. In order that it may be possible to-reset the indicating disks to zero Without any obstacle effected by` the starwheels a recess is provided in the circumferential surface of the calculating wheels respectively, according to this invention, which is located at the star-wheels respectively, when the calculating wheels have been turned to zero. In the saidposition the indicating disks must -be locked by latches, which, however, are disengaged immediately at the starting of the calculating wheels, at which moment the star-wheels take over the locking of theindicating disks.

In the accompanying drawings Figure 1 is an end view of a calculatingmachine arvention. Fig. 2 is a side view of a calculating wheel and the curve disk, rotatably mounted on the samefor the-'shifting of the pins; the said disk being shown in a position different from that shown in Fig. 1.

Figs. 13 and 14 are sections on a greater scale and on the lines 13 to 13, and 14 to 14 respectively of Fig. 1() and show` lfor finstance ytwo ten pins brought: into operative position. 'Fig 15 is a side view of the calculating wheel shown inV Fig. 8, parts belonging to the said wheel being omitted. l v

Y Ona shaft 1,Figs. 1 to 4 inclusive, journaled in the frame of the machine, are fixed, as usually, calculating Wheels 2, locatedat the side of one another. Only one of the said Wheels is shown in the drawings.. Radial pins or rods 3 are, as usual, slidably mounted in the wheel and may be brought into a projecting position by means of a ring-shaped, rotatable disk 4, Which is located at the side of the calculating Wheel and is shifted by means of a finger piece 5. The said ring 4 has tivo concentric slots 6, 7 opening into each other by a curved or inclined step 8, in Which slots lugs 9 on the pins 3 engage. The ring 4 is locked in ad justed position by a catch 10, which is pro vided in a sleeve 11, fixed to the shaft 1, and is held by a spring 12 in engagement with notches 13 in the ring 4. ln Fig. 1 all pins are shown in their retracted position. According to Fig. 2 thering 4 has been rotated into a position, in which it has brought three pins 3 into projecting position. As the calculating Wheel is rotated,Which is effected by rotating the shaft 1 by means of a crank not shown, the said three projecting pins engage the teeth of an intermediate Wheel 14 and turn the same a distance of three t cth, the said intermediate Wheel turning the registering Wheel 15, so that an indicating disk 16, connected with the said registering Wheel 15 and provided with ig-Y ures from O to 9 inclusive on its circumferential surface is turned a distance of three figures. rllhe figures are rendered visible in proper turn through an opening 17 provided in the casing 18 of a carriage 19, carrying the indicating disks and the said gear Wheels 14, 15. The said intermediate wheels and registering Wheels together with lthe indicating difsksV are rotatably mounted on shafts 14X and 15X respectively in the carriage 19. To the calculating Wheels 2 (eX- ccpt the calculating Wheel of the units) ten pins 20, 21, hundred pins etc. are pivoted, which are swingable transversely of the 'Wheels und are normally `held by a spring 22 to one side so as not to be inthe same plane of rotation. with the pins3 but for the carrying of the ten 7, the hundred etc. to the next column of value are del'lectedv and located in the said plane, so that the pins, While the calculating Wheels are rotated engage the intermediate Wheels 14 and t rn the saine the distance of one tooth. For effecting the said deflection the machine is provided with an arm 23 fulcrumed on a rod 23X in the carriage 19 and formed With a head 21W. The said head 23XX is brought into the plane of rotation of the ten pin by a pin 24, which is provided on the indieating disk belonging to the calculating Wheel for the units and acts upon a cam surface 25 on the head 23m, so that a cam surface on the head 23XX deflect-s the pin 20. The parts new described are found in Vcalculating, machines hitherto used and are which recess is located opposite to the tooth,

as shown in Fig. 1. The said recesses are formed with the same radius as the calculating Wheels 2 and the position of the star Wheel is so adapted, that the star-wheel bears against the circumferential surface of the calculating Wheel. As the calculating Wheel is in its normal position, shown in Fig. 1, a recess 38, provided in the circumferential surface of the calculating Wheel for the purpose stated below, is opposite to the star-Wheel 26. As soon as, however, the calculating Wheel is rotated from the position shown in Fig. 1, the star-Wheel 2G and, consequently, also the intermediate Wheel 14,the registering Wheel 15 and the indicating disk 1G are locked by the calculating Wheel. 1n order to render free the star-Wheel etc. While the projecting pins of the calculating Wheels pass the intermediate Wheel, the calculating Wheel is provided with means, effecting an opening in the circumferential surface of the calculating Wheel, through which the teeth of the starv Wheel can pass.

According to Figs. 1 to 4 inclusive the machine is arranged in the following manner for the accomplishing of the said purpose: The ring 4 is located in a lateral recess provided in the calculating Wheel 2, S0 that there is a flange 31 extending substantially around the ring 4 and covering the same. The said star-Wheel 26 bears against the said flange. The recess 38 mentioned above is provided in the said flange. Besides, a recess 32 is provided in the flange 31, extending along the set of nine pins 3 carried by the calculating Wheel. A flexible, curve shaped band 28 is fixed at its one end to a lug 29 on the ring 4, While its other end is located in a slot 30 in the circumferential surface of the calculating Wheel, which slot has a special shape for the purpose stated below. The inner edge of the band bears against the circumferential surface of the ring 4. Vhen the ring 4 together With band 28 is in the position, shown in Figs. 1 and 3, the bandA 28 extends along the Whole recess 32, from one end of the same to its other end and for some distance into the slot 30. The said band has such a position, that as the calculating Wheel is rotated and the recess 32 passes the star-Wheel, the band 28 will engage the star-Wheel and lock the same. `The Width of the star-Wheel is substantially equal to the Width of the band.

galateo As the ring 4 is rotated forfthrowingzout the desired number of pins 3, the band 28 is moved, so that an opening is provided between the end of the iange 31 an the lug 29, which opening is. located at the side of` f gages the intermediate wheel 14, the' opening 33 is at the star-wheel, so thatvthe latter is released and three `teeth of the same can pass through the opening, while the Vintermediate wheel 14 is rotated-by the calculating wheel a distance of 'three pins. *The star-wheel is then stopped again by the flange 31 or by the band 28, dependent yon the direction, in which the calculating wheel is rotated. As seen from 'the drawings, the opening 33 is always located at ythe projecting pins and the length of the same corresponds always tothe number of theprojecting pins. Consequently, if vfor instance eight pins are thrown out, the opening eX- tends along the set of the 4said eight pins and permits eight teeth of the star-wheel toy pass, before it is stopped a ain. 1'

As the ten pin 20 an 21 respectively, deilectedinto its operative position inthe manner described above, passes the starwheel,.an openingmust be provided in the flange 31, through which the star-wheel can pass. For that reason the ten pins (as wellas the hundred pinsV etc.)A are arranged as shown in Figs. 3.to 6 inclusive. An angular projection 34, 3'51respectively projects from the pin into .a recess 36, 37 respectively inthe flange 31 and the top ed e of thesaidrpro'ection is flush vwith the si e of the iiange.Y 7Vhile the pins 20, 21 are'in their normal position, Figs. 3 and Y4,the projections 34,35 constitute a continuation of the part of the flange 31 engaging the star-wheel. As, however, the t ten l pin is deflected Vby the head 23 x to run in the plane olf rotation of the pins 3,"the projection 34 or735 vrespectively is also deflected, so that the star-wheel can pass through the lopening 36 or 37 respectively, as the intermediate wheel lis rotated by the ten` pin. The length of the openingsy 36, 37l lis so adapted, that only one tooth of the star-wheel can pass through the same and the star-wheel subsequent to the rotation, islocked a' in bythe calculating wheel. `The length o the project-ions 34,35 is substantially Vequal to the length of fthe openings. For making Vroom for'the opening 36in-the ange 31,

the slot 30 forrthe band 28 is shaped as Aiterthe calculation has been effected, all indicating disks must beflreseft to zero, as usual, which is effected by rotating the shaftv 15", Vwhich then is shifted longitudinally, in known manner, andby means `of pins engages the indicating disks. While the indicating disks are turned to zero, the intermediate wheels together with the starwheels must be able to rotate without being prevented by the calculating wheels. For that `reason the opening 38, Fig. 1, is provided in the ilange 31 of the calculating wheels respectively, which, when the calculating vwheel is in Zero, is atv the star-wheel. As soon as, however, the calculating wheel is rotated for effecting the calculating operation, the opening 38 is moved from the star-wheel and the latter is then locked by the vcalculating; wheel in the manner described above. 58 is the ordinary cam piece provided on the calculating wheel vforreturning the arm 23 with the head 23Xx into its inactive position. The said arm is held in 4its operative and inoperative positions respectively by a catching device, not shown.

'39 is rod 'rotatably mounted in the carriage 1f9,fro-m which arms 40 extend, which engagethe registering wheels 15 respectively and lock the same and the indicating disks 16. From the said rod 39 arms 41 extend, which carry a bar 42, which is engaged by one 43 of the arms of a two-armed lever 43, 44, pivoted to the frame of the machine. The other arm A44 of the said lever is provided with aV roller 45, which bears against a disk 46, rotating with the calculating wheels'and provided with a notch 47. lVhile fthe calculating wheel is in zero position, the roller 45 engages the said notch 47 and the gagedand thus effect noresistance against `the rotation of the wheels.

said fact the calculating machine runs very easily and the catches effect no noise. The

said catches lock the registering wheels and the indicating disks only while the calculating wheelsrare in zero position. As soon as the calculating wheels are rotated from the 'said position, the calculating wheels thernselves takeover the locking function. y

'In' the form of the invention shown in Figs. 8 to 15 inclusive one portion of the star-whee126, transversely of the same, bears against the `circumferential surface or edge of the lcalculating wheel- 2, while the Owing to the other portion of the star-wheel can bear against the ring 4, adapted to shift the pins 3. In the edge of the calculating Wheel 2 a recess 49 is provided, which extends along the whole set oi pins 3. As the said recess 49 passes the star-wheel during the rotation of the calculating wheel the star-wheel engages only the ring 4, which ring for a part of its circumference has the same radius as the calculating wheel. The said part is divided into radial tongues 50 for the purpose statedbelow. In Figs. 8 and 9 the said ring 4 `is shown in its starting position. lin the said position the set of tongues extends along the wholerecess 49 and to the ten pin 20. As the ring is shifted for throwing out for instance three pins 3, as shown in Figs. 10 and 11, an opening or gap 51 is effected at the said three pins, at whichthe star-wheel is engaged neither by the calculatingwlieel nor by the tongues of the ring 4. Consequently, while the said three pins rotate the intermediate wheel and the registering wheel together with the indicating disk, three teeth oi? the star-wheel can pass through the gap 51, the star-wheel being then locked again by the tongues of the ring 4 or by the calculating wheel, dependent on the direction, in which the calculatingwheel is rotated. Also in the present form of the invention openings must be procured, through which onel of the teeth of the starwheel can pass, as the ten7 pins etc. are brought into operative position. rIhis is effected by the ten pin 20, which is located in a recess 52 in the circumferential surface of the calculating wheel, having a pin 53,

which, as the pin 2O is brought into its oper-y ative position, defiects one of the tongues 50 of the ring 4, located opposite to the ten l pin, as shown in Fig. 14, so that the said tongue ceases to form an abutment 'for the star-wheel. One of the teeth of the latter may then pass through the gap, while the pin 20 rotates the intermediate wheel and the star-wheel. The latter is then locked by the calculating wheel and also by the tongues of the ring 4. Also the second ten pin 21 of the calculating wheel is movable in an opening or recess 54 in the calculating wheel and is provided with a pin 55, which, as the pin 21 is brought into its operative position, detlects a tongue 55, nxed to the hub oi the calculating wheel 2. The said tongue 56 has a lateral projection 56X, which, as the tongue 56 is in its normal position, is located in the same plane as the tongues 50 of the ring 4 and consequently locks the star-wheel, as the ten pin 2l passes the same, see Fig. 12. It, on the other hand, the pin 21 is inits operative position, it keeps the tongue 56 in the position shown in Fig. 13, so that the star-wheel may be rotated `a distance of one pin.

As seen from the above description, the

registering wheel together with the indicating disk is, in both forms of the invention, perfectly locked by the star-wheel and the calculating wheel, until the projecting pin or pins ofk the latter eiect the shifting of the indicating disks. Immediately after the said shiftingv the indicating disk is locked again bythe star-wheel. Even if the calculatingwheel is rotated very rapidly, the intermediate wheel, the registering wheel andthe indicating disk are locked by the star-wheel in the most reliable manner and may not be moved beyond the new position by the momentum imparted to the same. Owing to the said fact and the fact thatthe star-wheel normally. is locked, while the .ten pins, etc., pass the same, the machine operates in the most reliable manner.

Having now described myinvention, what I claim as new and desire to secure by Letters Patent is:
